Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Use) The present invention relates to a license plate mounting structure for mounting a license plate on the front side of a front bumper of a vehicle such as an automobile.

(Prior Art) FIG. 4 shows a front portion of an automobile having a design that has been frequently seen recently, and a large front bumper 2 is provided on a front portion of a vehicle body 1. This front bumper 2
Is generally composed of a synthetic resin bumper face 3 and a bumper beam 4 which is disposed inside the bumper face 3 as shown in FIG. The bumper beam 4 is made of a metal such as aluminum having a high rigidity and has a cross-section shape of a cross section. The bumper beam 4 is long in the vehicle width direction, and both ends thereof are attached and held to a strength member of the vehicle body through stays and dampers. ing. The bumper face 3 which is attached so as to cover the front surface of the bumper beam 4 is of a soft fascia type which also serves as a front grill and an apron of the vehicle body 1, and has a radiator cooling air intake 3a opened in the center. .

In an automobile using such a front bumper 2, in order to mount the license plate (license plate) 5 on the front side, the bracket must be projected forward from the bumper beam 4 through the air intake port 3a, and the license plate 5 must be mounted on the bracket. .

By the way, in some US NAS, it is not necessary to attach the license plate 5 depending on the state. In that case,
It looks bad if only the bracket is protruding forward.
In order to solve this, as shown in FIG. 5, the bracket is divided into a first bracket 6 and a second bracket 7, and the first bracket 6 is fixed to the front part of the bumper beam 4. The bolt 6 is fastened and fixed, and the following extending portion 6a of the first bracket 6 is obliquely projected to the inner position of the air intake 3a below the bumper beam 4. On the other hand, the second bracket 7 has a substantially L shape, and the rear end bent portion of the lower horizontal plate portion 7a is passed through the air intake port 3a to be joined to the lower extension portion 6a of the first bracket 6. Then, it is fastened with the detachable bolt 9. And this second
The license plate 5 is attached to the front surface of the front rising plate portion 7b of the bracket 7.

When it is not necessary to attach the license plate 5, the detaching bolt 9 is removed, and the second bracket 7 is completely removed from the first bracket 6 for better appearance.

(Problems to be Solved by the Invention) In the conventional license plate mounting structure described above, the first bracket 6 is mounted on the front surface of the bumper beam 4 of the front bumper 2. In addition, since the bumper beam 4 is made of aluminum and cannot be welded, a fixing bolt 8 is used, so that a tightening work hole 10 (having a diameter of about 20 mm or more) 10 is formed on the back surface of the bumper beam 4. For this reason, when an impact force is applied to the front bumper 2 due to a rear-end collision or the like, first, the resin bumper face 3 is deformed as shown in FIG.
The fixing bolt 8 and the first bracket 6 projecting to the front side will be hit, and the bumper face 3 will be damaged there.

Not only that, the impact force F is concentrated on the central portion of the bumper beam 4 via the fixing bolt 8 and the first bracket 6 as shown in FIG. The side part receives a compressive force from the left and right, and the back side part receives a tensile force in the left and right directions. Moreover, since the working hole 10 exists on the back side receiving the pulling force, the tensile strength is weak. The bumper beam 4 may be broken in the middle as shown in FIG. 7 (b) and may be damaged before the impact force F is sufficiently absorbed.

The present invention has been made in view of the above circumstances. The purpose of the present invention is to attach / detach the second bracket according to whether or not the license plate is attached, as in the conventional case, and in the case of a rear-end collision. An object of the present invention is to provide a license plate mounting structure capable of preventing damage to the bumper face even when it receives an impact force from the front side, and reinforcing the bumper beam to prevent center-fold damage.

[Constitution of device]

(Means for Solving the Problems) In order to achieve the above object, the present invention attaches a first bracket to a bumper beam of a front bumper arranged on the front surface of a vehicle body, and attaches a first bracket to a lower extension portion of the first bracket. In a license plate mounting structure in which the second bracket is mounted in a state of protruding to the front of the front bumper via a detaching bolt, and the license plate is mounted to the second bracket, the first bracket is attached to the bumper beam. This is because it is attached to the back surface and the lower extending portion of the first bracket is projected below the bumper beam.

(Operation) According to the license plate mounting structure described above, the first
The bracket was attached to the back of the bumper beam of the front bumper, but the lower extension of this first bracket projects below the bumper beam. The second bracket can be easily attached to and detached from the first bracket.

Further, as described above, since the first bracket is attached to the back surface of the bumper beam, there is no protruding portion like the conventional fixing bolt on the front side of the bumper beam,
Even if the bumper face is deformed by the impact force F from the front in the case of a rear-end collision accident, the perforated damage is eliminated, and the impact force F is less likely to be concentrated in the central portion of the bumper beam. Moreover, the first bracket is attached to the back side portion of the bumper beam where a tensile force is generated by the impact force F from the front side, and this serves as a reinforcing material.

Therefore, there is no concern that the bumper beam is easily broken and broken as in the conventional case, and the impact force F can be sufficiently absorbed.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In the drawings, the same components as those shown in FIGS. 4 to 7 are designated by the same reference numerals to simplify the description.

Here, FIG. 1 is a cross-sectional view of the front bumper 2, and FIG. 2 is a perspective view of the bumper beam 4 as viewed from the rear side.
3A and 3B are plan views showing a deformed state of the bumper beam 4 with respect to an impact force.

First, as shown in FIG. 1, as a front bumper 2, there is a bumper face 3 made of a synthetic resin integrally molded product as in the conventional case, and a bumper beam 4 arranged on the inner upper side of the central air intake 3a of the bumper face 3.

As a structure for mounting the license plate 5 on the front bumper 2, a first bracket 11 and a second bracket 11 are provided.
The bracket 12 is provided.

As shown in FIGS. 1 and 2, the first bracket 11 is fastened and fixed to the central portion of the rear surface of the bumper beam 4 by a plurality of fixing bolts 13 also for reinforcement. The first bracket 11 is an angle member bent from the back surface of the bumper beam 4 along the bottom surface, and a pair of left and right lower extension parts 11a are bent downward from the front end of the bottom plate portion in a substantially V shape. It is projected.

A mounting hole is formed in the lower half portion 11b of the lower extending portion 11a, which is inclined rearward, and the second bracket 12 is formed in the lower half portion 11b.
A rear end bent portion 12a 'of the lower horizontal plate portion 12a is joined and fastened by a detaching bolt 9. The second bracket 12 is similar to the conventional one described above, and the front rising plate portion 12
b The license plate 5 is attached to the front surface with screws or the like.

Reference numeral 14 in the drawing denotes a work hole for tightening the fixing bolt 13, which is formed in the front portion of the bumper beam 4.

Next, the operation of the license plate mounting structure having the above-described structure will be described.

Although the first bracket 11 is attached to the back surface of the bumper beam 4, the lower extension 11a of the first bracket 11 projects near the inner side of the air intake 3a below the bumper beam 4, so the license plate Depending on the presence or absence of 5
Through the inner space of the air intake port 3a, as shown by the arrow, by inserting a hand, the detaching bolt 9 can be easily removed and tightened with a tool such as a wrench. Therefore, when the mounting of the license plate 5 is not necessary, the detaching bolt 9 is removed, the second bracket 12 is completely removed from the first bracket 11, and the appearance of the front of the vehicle body is ensured.
When the license plate 5 is required, the second bracket 12 is attached to the first bracket 11 and the license plate 5 is attached.

Since the first bracket 11 is attached to the back surface of the bumper beam 4, there is no projecting portion on the front side of the bumper beam 4 unlike the conventional fixing bolts, and the bumper face can be formed by the impact force from the front in the event of a rear-end collision. Even if it is deformed, the perforated damage is eliminated, and the impact force is less concentrated on the central portion of the bumper beam 4. In addition, the first bracket 11 is attached to the back side of the bumper beam 4 where a tensile force is generated by the impact force from the front, and this serves as a reinforcing material.

Therefore, there is no concern that the bumper beam 4 is easily broken and broken as in the conventional case, and the impact force can be sufficiently absorbed.

[Effect of device]

Since the license plate mounting structure of the present invention is configured as described above, the workability of attaching and detaching the second bracket can be as simple and convenient as before, depending on whether the license plate is attached or not, and the front side can be used in the event of a rear-end collision. Even if it receives an impact force from
In addition, the effect of reinforcing the bumper beam and preventing breakage of the center fold can be obtained.
